VERTICAL. WATER-TUBE BOILER.

Application filed May 8,

To'aZZ whom it ma concern:

.Be it known that I, GLENvrLLn J. G. LAGEY, a subject of the King ofGreat Britain, and a citizen of the Dominion of Canada, residing at thecity and county of Kalamazoo, State of Michigan, have invented certainnew and useful Improvements in Vertical W aterTube Boilers, of which thefollowing is a specification. g I 1 This invention relates toimprovements in vertical water tube boilers, that might properly becalled amodified vertical water tube boiler. A v

The objects of the invention arei First, to provide an improved construction of water tube boiler in which the heat units developedin thefirebox or furnace will be more effectively utilized.

Second, to providean improved construck tion and arrangement'of watertubes in a water tube boiler.

Qbjects pertaining to details and economice of construction andoperation will definitely appear fromthe detailed description tofollow.p

I accomplish the objects of my invention bythe devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims. A-structure which isa preferredembodiment of my invention is fully illustrated in the accompanyingdrawing, forming apart of this application, in which; i

Fig. I is a detail central sectional elevav tion view takenon line 1-1of Figs. II and III, the boiler'and tube portions being shown in fulllines and the position of certain parts being indicated by dotted lines,'thecasing and partition walls andfootings being in section. p p

Fig. II is an enlarged plan view of the boiler andtube parts appearingin Fig. I, the casing and footings being omitted. a Fig. III'is a detailsectional view through the bridge wall'taken on the irregular line "ofFig. I, showing the flue openings therethrough.

In the drawings thesectional views are taken looking in the direction ofthe little ai'rowslat the ends of the section lines and similarnumerals'of reference refer to similar parts throughout thejseveralviews.

Referringgto the numbered parts of the drawing, 1 is theupper drum of avertical.

usual water tubes between the base and upper drum. dis the usual casingsurroundmg the same. 5 is the firebox or furnace, preferably providedwith an automatic stoker 6 with the ashpit 7 below. 8 the footlng wallsfor supporting the boiler and 9 the bridge wall having a series of 'fiuepassages 10 therethroughfor delivering heat and the products ofcombustion directly into the front of the boiler. 11 is the verticalpartition extending from the base 2 up towards the top drum 1 to compelthe products of combustion to ascend through the tubes, pass over thepartition wall and then down to the flue opening 12, which leads to thestack 13. These parts, with the exception of the bridge wall, are in ausual form of water tube boiler. w

14 is an auxiliary header disposed transversely to the lower frontportion of the upright tubes of the boiler and having a portion of thetubes 15 deflected and connecting therefrom to the top drum, and anotherportion 16 connecting from the base and deflected and connected to thesaid header 1 1. 17 is the front header of the boiler resting upon thefront wallof the furnace, 18 a series of obliquely disposed water tubesextending. from their front header 17 upwardly and rearwardly to theauxiliary header 1 1. A transversely disposed partition 20 divides therear portions of the boiler tubeslS into an upper and lower groupaffording a double passage for the products of'combustion which passdirectly up from the firebox 5, these water tubes being'disposeddirectly above the firebox. An oblique casing 19 closes the top of thechamber within which the oblique water tubes are disposed, the samebeing closely conformed thereto to retain and guide the heated productsof combustion in close relation to the said pipes and deliver themthrough the passage way 14; above the header 1 1. A considerable part ofthe productsof combustion are delivered underneath the header because ofthe deflecting partitionwall 20. p

21 is a pipe connection to the bottom of the boiler. 22 is a blow outpipe from the bottom of the-header, 17, and 23 is a feed pipe connectingto the top of the header 17 the same being associated with the usualfeed pipe 23 for delivering water to the m i pa t f the boiler. 2 is aci u a i n pipe from the header 14 to the top drum l of the boiler. .isa water columngage at the top drum of the boiler.

I have shown my improved water tube boiler in the form preferred by me,but desire to state that it can be considerably varied in its detailswithout departing from my invention. I desire to clalm thesame 1n theprecise form in which I have illustrated it and also desire to claim thesame broadly as pointed out in the appended claims,
